8.3.1. Disconnecting the VF from the VM and Reconnecting to the PF
- Uninstall the driver on the VM:
sudo yum remove opae-intel-fpga-driver.x86_64
- Detach the VF from the VM.
On the host machine, unbind the VF PCI device from the vfio-pci driver:
sudo sh -c "echo -n 0000:04:00.1 > /sys/bus/pci/drivers/vfio-pci/unbind"
- Bind the VF to the intel-fpga driver:
sudo sh -c "echo -n 0000:04:00.1 > \ /sys/bus/pci/drivers/intel-fpga-pci/bind"
- To ensure you have the correct $pci_path for disconnection, type:
export pci_path=/sys/class/fpga/intel-fpga-dev.*/device
To target PCIe B:D.F (AF:00.0) and B:D.F (37:00.0) in the following commands, use instance id 1 and 0 instead of * respectively.
- Set to 0 VFs and disable SR-IOV:
sudo sh -c "echo 0 > $pci_path/sriov_numvfs"
- Assign the port to the PF using the fpgaport tool:
sudo fpgaport assign /dev/intel-fpga-fme.* 0 --numvfs 0
